多层隔热材料传热特性研究现状及展望

摘要

研究多层隔热材料的传热特性是进行航天器热控设计的基础.文章首先介绍了多层隔热材料的分类和应用情况,及其传热方式和隔热性能表征方法;然后评述了多层隔热材料传热特性和空间环境适应性的研究状况,总结了相关研究方法、热分析模型与研究得出的基本认识;最后,提出了多层隔热材料热特性的进一步研究方向.%The knowledge of the heat transfer characteristics of multilayer insulation materials is essential for the design related with the thermal control and the heat reservation (insulation).This paper discusses first the classification and the application fields of multilayer insulation materials,then their heat transfer mechanism and the characterization methods.After that,the research advances in the thermal characteristics and the space environmental applications of multilayer insulation materials are reviewed,including the methods,the thermal models and typical results.Suggestions of future research areas of the heat transfer characteristics of multilayer insulation materials are made.
